As a reminder, AMD use to do this to AIBs often, giving them samples with different bioses so if there's leaks, it's wrong info (not final SP count or clocks!) on purpose and they know who is reliable. They give them the final bios just shorty before products are finalized.
Interesting that they do this to reviewers as now as well for Polaris... really secretive launch. Since everyone was shocked about the pricing, I think AMD's goal was to catch NV with their pants down basically.
I think NV was on to this, hence the dual pricing, MSRP/Ref. So if Polaris is good, and NV needs to price drop, they don't have to, simply have cards sell for MSRP and claim "our MSRP has not changed".
Thinking about it, it's entirely plausible all the leaked CU count so far for C4, C7 and C10 could be ALL WRONG.
Btw, with all the eyes of tech journalists on him, Raja pulls out victory cigar.
